MACHINE FOR DELINTING COTTON-SEED.

SPECIFICATION forming part of Letters Patent No. 430,496, dated June 17, 1890.

Application filed December 9, 1889. Serial No. 333,115. (No model.)

To all whom it may concern:

Be it known that we, JOHN IV. VATKINS and JAMES S. COOHRAN, citizens of the United States, residing in the city an d county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Machines for Delinting Cotton-Seed, which improvement is fully set forth in the following specification and accompanying drawings.

Our invention consists of improvements in machines for cleaning or delinting cottonseed, the several features thereof being hereinafter fully set forth, and definitely pointed out in the claims.

Figure 1 represents a partial side elevation and partial vertical section of two machines for cleaning or delinti n g cottonseed, showing our invention. Fig. 2 represents a top or plan view of one of the machines and connected parts. Fig. represents a side elevation of the machine parts shown in Fig. 2, showing portions of the same in section. Fig. 4 represents a side elevation of the brush of the machine, part of the same being separated. Fig. 5 shows a side elevation of a connected series of machines.

Similar letters of reference indicate corresponding parts in the several figures.

Referring to the drawings, A designates the frame of the machine, and B designates a conical casing, which is mounted therein and having within the same the brush C, the latter consisting of a cone-shaped backing D, with brush material thereon, said material being formed of a strip E, of leather or other suit-- able material, with wires or teeth F attached thereto, the strip being wrapped around the backing and fastened by a wire or cord G, which is wound spirally around the strip in the space between the wires or teeth thereof, and secured at its ends by staples G, as shown in Fig. 4, which are driven through the strip into the backing and embrace the wire, the strip thus being most firmly bound to the backing and securely held thereon.

ll. designates a feed or supply box, which is located adjacent to the casing B, and into the same dips the endless conveyor J, which is supported on a suitable frame K, and is operated by a wheel or pulley K, (shown in dotted lines, Figs. 2 and 3,) to which power is suitably communicated. The buckets L of the conveyer discharge into a chute M, which is located above the casing B and communicates with feed-openings N in the top of said casing, whereby the latter may be supplied with seed to be cleaned or delinted.

The casing 13 has a hinged door P, whereby access is had to the interior of said casing and the brush, it being noticed that. the inner surface of the casing is clad with brush material Q, preferably wire.

The brush 0 is rotated in any suitable manner, it being noticed that in the drawings its shaft is mounted on the frame A, and carries a pulley O for rotating said brush.

\Vhen the machine is in operation, the seed is carried from the box II by the conveyer J to the chute or receptacle M, and thus directed through the openings N into the easing B, where it is subjected to the brush therein,and thus cleaned or delinted. Below the brush is a box R, within which is a chute or deflector S, the said box being in communication with the open bottom of the casing B. The box R opens into a seed box or receiver T, into which dips the endless conveyer U of any preferred construction, and consisting in this instance of buckets R, attached to flexible side supports R passing over rollers, pulleys, or sprocket-wheels T, and said buckets discharge into an elevated conveyer V. The box R has connected with it a funnel WV, which leads to a blower or exhaust-fan X, from which leads a dischargepipe Y. It will now be seen that as the seed cleaned or delintcd leaves the brush and falls through the opening in the bottom of the casing it is directed by the chute S into the box R and drops into the receiver T, after which it is taken up by the conveyer U and deposited into the conveyor V, said conveyer V, which may be of any preferred construction and operated as may be desired, being shown as composed of flexible side supports V passing around pulleys, rollers, or sprocket-whecls V and carrying floats V Simultaneously therewith the blower or fan X draws the lint from the casing B through the box R and tunnel \V, and directs the same into the pipe Y, by which it may be discharged elsewhere.

It is important to employ large volumes of air in order to clt'ect the proper discharge of the linttrom the casing. Forthis purpose we form in the top of the casing inlets Z, in the side of the tunnel \Y an inlet Z, and in the side of the box R an inlet Z so that a-irmay be drawn into and through said casing, box, and tunnel, and thus ellectively carry away the lint thrtnigh the blower or fan. The vent or inlet Z in funnel \V is provided with a movable covcrZ, and may be opened or closed to coi'npensate for variations in barometric pressure. \Vhcn the pressure is high, the said vcntis opened to prevent upward suction of the seed with the lint, and when the pressure is low the vent or inlet is closed to establish suilicient suction to raise the lint.

'lhe inlets are preferably guarded by gauze or netting to prevent the entrance of improper matter into the casing ll. The fan Z Fig. 1, aids in blowing the lint from the seed passing over the chute S by directing a blast thereon through the opening in the bottom of casing B.

In Fig. l we show a duplication of the machine, the seed passing through first one ma chine and then the other, and in Fig. 5 atriplication of the same.

\Vhen a batteryof three machines is used, the seed is placed in the first two machines and delinted, and the cleaned seed therefrom unitedly delivered into the third machine by being deposited on the conveyor V from said first and second machines, and from said convcyer V being carried by chute V, leading to the seed-receiving-b0x ll of the third machine, where the delinted seed is further subjected to a cleaning action. If desired, the seed may be placed in the first machine and successively cleaned in the remaining inachines composing the battery.

In practice the brush of the first machine is somewhat coarser than those of the other machines of the series or team, so that the cleaning or delinting may be gradually aceomplished.

Having thus described our invention,what

we claim as new, and desire to secure by Letters latent, is

l. A brush for delinting or cleaning cottonseed, composed of a backing or body having wound thereon a strip of card or brush clothing composed of a backing provided with wires or teeth inserted therein, and having said strip bound to the backing by a cord or wire wound upon the same and lying between the teeth, substantially as described.

2. A machine for delinting or cleaning cotton-seed, consisting of a casing with a brush on the inner surface thereof and a revolving brush within the same, said revolving brush consisting of a body, a strip of toothed material wound thereon, and a binding wire or cord wound upon said strip and secured to said body, substantially as described.

A machine for delinting or cleaning cotton-seed,having a revolving brush consisting of a conical body, a strip of toothed material wound thereon, and a binding wire or cord wound upon said strip and secured to said body, and a casing conforming to said brush and having an inner brush-surface, substantially as described.

4. An organized machine for delinting or cleaning cottonseed, having a casing with a brush therein, a box for receiving the cleansed seed, and a tunnel or pipe leading from said box to a blower or fan, said casing, box, and funnel having air-inlets, substantially as described.

5. A battery of machines for delinting or cleaning cotton-seed, each having a casing with a brush on the inner surface thereof and a revolving brush within the same, a seed-receiving box, and asuction funnel or pipe leading .lroni said box, said casing, box, and funnel having air-inlets, an elevator leading from the seed-discharge box of one machine, and a couveyerrcceiving the seed from said elevator and leading to a feed-opening of another machine, substantially as described.
